An aluminum wheel and a manufacturing method thereof are provided to improve the vibration absorption ability by manufacturing a hollow rim part by the aluminum extruding process and the laser welding process. An aluminum wheel comprises: a spoke(20) formed by aluminum low pressure casting; and a rim part(30) having a hollow part at an outer tip end part. The outer part of the spoke and an inner end part of the rim part are formed integrally by MIG welding. A through hole is formed at least one in the hollow part of the rim part to deliver the pressure applied to tire to the hollow part. |
